MC78L05ACDR2G from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VOUT	power_out	Regulated +5.0 V output (4.8-5.2 V typ at 25 degC). Sources up to 100 mA. Recommended 0.1 uF ceramic to GND for transient response (not required for stability).
2	GND	power_in	Ground reference. Electrically common to die attach flag along with pins 3, 6, 7 for improved thermal dissipation; connect all four to the ground copper pour.
3	GND	power_in	Ground reference. Electrically common to die attach flag along with pins 2, 6, 7; connect to ground copper for thermal dissipation.
4	NC	unconnected	No internal connection. Leave floating or tie to ground.
5	NC	unconnected	No internal connection. Leave floating or tie to ground.
6	GND	power_in	Ground reference. Electrically common to die attach flag along with pins 2, 3, 7; connect to ground copper for thermal dissipation.
7	GND	power_in	Ground reference. Electrically common to die attach flag along with pins 2, 3, 6; connect to ground copper for thermal dissipation.
8	VIN	power_in	Unregulated positive input. Absolute max 30 Vdc for the 5 V version; typical operating range 7 V to 20 V. Recommended 0.33 uF ceramic to GND if regulator is remote from the bulk supply filter.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc78l05acdr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`mc78l05acdr2g-etched.step`	2.6 MB	You want the part with `MC78L05ACDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 641 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
